bokeh.server.auth_provider

Provide a hook for supplying authorization mechanisms to a Bokeh server.

class AuthModule(module_path: PathLike)

An AuthProvider configured from a Python module.

The following properties return the corresponding values from the module if they exist, or None otherwise:

• get_login_url,

• get_user

• get_user_async

• login_url

• logout_url

The login_handler property will return a LoginHandler class from the module, or None otherwise.

The logout_handler property will return a LogoutHandler class from the module, or None otherwise.

Public Data Attributes:

get_user	A function to get the current authenticated user.
get_user_async	An async function to get the current authenticated user.
login_url	A URL to redirect unauthenticated users to for login.
get_login_url	A function that computes a URL to redirect unathenticated users to for login.
login_handler	A request handler class for a login page.
logout_url	A URL to redirect authenticated users to for logout.
logout_handler	A request handler class for a logout page.

Inherited from AuthProvider

endpoints	URL patterns for login/logout endpoints.
get_login_url	A function that computes a URL to redirect unathenticated users to for login.
get_user	A function to get the current authenticated user.
get_user_async	An async function to get the current authenticated user.
login_handler	A request handler class for a login page.
login_url	A URL to redirect unauthenticated users to for login.
logout_handler	A request handler class for a logout page.
logout_url	A URL to redirect authenticated users to for logout.

property get_login_url

A function that computes a URL to redirect unathenticated users to for login.

This property may return None, if a login_url is supplied instead.

If a function is returned, it should accept a RequestHandler and return a login URL for unathenticated users.

property get_user

A function to get the current authenticated user.

This property may return None, if a get_user_async function is supplied instead.

If a function is returned, it should accept a RequestHandler and return the current authenticated user.

property get_user_async

An async function to get the current authenticated user.

This property may return None, if a get_user function is supplied instead.

If a function is returned, it should accept a RequestHandler and return the current authenticated user.

property login_handler

A request handler class for a login page.

This property may return None, if login_url is supplied instead.

If a class is returned, it must be a subclass of RequestHandler, which will used for the endpoint specified by logout_url

property login_url

A URL to redirect unauthenticated users to for login.

This proprty may return None, if a get_login_url function is supplied instead.

property logout_handler

A request handler class for a logout page.

This property may return None.

If a class is returned, it must be a subclass of RequestHandler, which will used for the endpoint specified by logout_url

property logout_url

A URL to redirect authenticated users to for logout.

This proprty may return None.

class AuthProvider

Abstract base class for implementing authorization hooks.

Subclasses must supply one of: get_user or get_user_async.

Subclasses must also supply one of login_url or get_login_url.

Optionally, if login_url provides a relative URL, then login_handler may also be supplied.

The properties logout_url and get_logout_handler are analogous to the corresponding login properties, and are optional.

Public Data Attributes:

endpoints	URL patterns for login/logout endpoints.

This property may return None, if a get_user function is supplied instead.

If a function is returned, it should accept a RequestHandler and return the current authenticated user.

property login_handler: Type[RequestHandler] | None

A request handler class for a login page.

This property may return None, if login_url is supplied instead.

If a class is returned, it must be a subclass of RequestHandler, which will used for the endpoint specified by logout_url
